SYSTEM FOR ELECTRICALLY POWERING ELECTRICAL EQUIPMENT OF A MOTOR VEHICLE WITH A HIGH PERFORMANCE BATTERY, CORRESPONDING CURRENT LIMITATION DEVICE AND EQUIPPED STARTER.

摘要

The electrical power supply system (10) of electrical equipment by a high performance battery (2) is of the type of those comprising at least one limiting device (LPF) of a current of the high performance battery. The high performance battery has a first nominal voltage higher than that of a standard battery initially provided for powering equipment that includes a starter (8) of a heat engine connected to the high performance battery through the limiting device. According to the invention, the limiting device (LPF) is a transformer comprising a secondary winding circuit (R, W2) formed by a secondary winding (W2) short-circuited. According to another characteristic, the transformer has a coupling coefficient and a secondary resistance of the secondary winding circuit which are a function of specific characteristics of the equipment.
